Oiltech Controls’s Insight
- This RTD board excels in turbine and generator temperature monitoring.
- Noise suppression ensures stable readings in high-EMI environments.
- Choose TRTDH1C for simplex VRTD applications – cost-effective and reliable.
- For redundant systems, consider TRTDH1B (TMR) or TRTDH2D (quick-scan).
- Always verify cable resistance stays below 15 ohms for accuracy.
Suitable Equipment
- GE Mark VI turbine control systems.
- Gas and steam turbine temperature monitoring.
- Generator stator and bearing RTD inputs.
- Industrial process heating/cooling loops.
- Power plant auxiliary systems.
Professional FAQ
- Q: What is the maximum cable length for RTD inputs?
A: Keep total lead + cable resistance under 15 ohms. Use heavy gauge wire for longer runs. - Q: Can I mix different RTD types on one board?
A: No. Each board supports one RTD type per configuration. Choose the correct variant for your sensor. - Q: How do I verify the board’s health during maintenance?
A: Check fault LEDs and run software diagnostic tests. Monitor ID chip status for early warnings. - Q: What is the difference between TRTDH1C and TRTDH1D?
A: TRTDH1C uses DC-type VRTD connectors; TRTDH1D uses PRTD normal scan connectors. Select based on your RTD type. - Q: Is this board compatible with older Mark V systems?
A: No. It is specifically designed for Mark VI. Use appropriate interface if retrofitting.
